Answer:
7
Step-by-step explanation:
It is 7 because when you go to 0.7 mph you go over until you reach 7 min.
Answer:
f(x) = (2/3)x + 4
Step-by-step explanation:
An equation in function is found by isolating y, and changing "y" to "f(x)".
Isolate y by moving everything else to the other side
What is done to one side must be done to the other
6y - 4x = 24
6y - 4x + 4x = 24 + 4x (add 4x to both sides. -4x +4x cancels out)
6y = 24 + 4x
6y/6 = 24/6 + 4x/6 (divide both sides by 6)
y = 4 + (2/3)x (simplify)
y = (2/3)x + 4 (rearrange to a familiar format "y=mx+b")
f(x) = (2/3)x + 4 (replace y with f(x))
So the equation for a trapezoid is

, with the b variable being the 2 bases, h variable for height, and the a variable for area. Firstly, we will need to plug in the appropriate numbers into the equation, and it'll look like this:

Next, we will need to combine 12 and 14, then divide the sum by 2. Your equation should look like this:

Lastly, just divide each side by 13, and your answer should be
Answer:
9/25
Step-by-step explanation:
Number of Trials =50
<u>Outcomes Less than 4</u>
Frequency of 1=6
Frequency of 2=4
Frequency of 3=8
Total =6+4+8=18
Relative frequency for "roll a number less than 4" =18/50=9/25
Well a markup is the amount added to the current price so 75% added to 27$ then subtract 40%
